Needing Some Help!

I am now turning to my internet brethren for godly wisdom and advice on writing my dissertation. My topic is the importance of prayer in the preparation of the expository, biblical sermon. If you have any thoughts or can recommend sources from books or magazines please email me at pastorcbc@mchsi.com Thank you for any suggestions!

I might add that I want to concentrate on the lives of Steve Lawson, CH Spurgeon, and DL Moody regarding this area.
